Question

a man banana at the rate of 8 rupees for 10 piece and sold them at the rate of 10 rupees for 8 piece how many bananas should he sell the profit 90 Rupees​

Answer 1

Answer:

200 bananas.

Explanation:

According to the question,

CP of 1 banana is 8/10

SP of 1 banana is 10/8

Profit on one banana is (10/8) - (8/10) =

(take a LCM of 10, 8 = 40)

Now,

50- 32/ 40 = 18/40 = 9/20

In Rs. 9/20 a man can buy 1 banana

So, In Re. 1 a man can buy 20/9 banana

And In Rs. 90 a man can buy (20/9)× 90= 200 bananas.
